System and method for time-frequency separation of multiple radio signals

A method for time-frequency separation based on image analysis of one or more spectrograms of multiple radio signals received over time from one or more emitters, the method comprising:

• determining, by a processing circuitry, using image analysis, a region of at least one of the spectrograms containing representations of a superposition of two or more overlapping radio signals of the radio signals, the overlapping radio signals being representations of radio signals sharing a common time-frequency within the at least one of the spectrograms;
• decomposing, by the processing circuitry, the superposition of the two or more overlapping radio signals within the region into separate signal representations, wherein each given separate signal representation of the separate signal representations is expressed by a corresponding bounding box around the given separate signal representation;
• determining, for at least one separate signal representation of the separate signal representations, one or more parameters based on the corresponding bounding box;
• and
• performing, by the processing circuitry, utilizing the separate signal representations and the parameters, one or more actions.

A non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code, executable by at least one processing circuitry of a computer to perform a method for time-frequency separation based on image analysis of one or more spectrograms of multiple radio signals received over time from one or more emitters, the method comprising:
